Description

Technical Field

[0001] This utility model relates to the field of pulverizer technology, and in particular to a high-speed pulverizer. Background Technology

[0002] A high-speed pulverizer is a mechanical device that rapidly grinds materials using high-speed rotating metal blades. These devices are typically used to process solid materials such as plastics, chemical raw materials, food, and medicinal materials into fine or uniform particles or powders. Most high-speed pulverizers are made with robust structures and high-quality materials, possessing strong wear resistance and durability. However, a small amount of material may still be produced that is not properly pulverized during the pulverization process.

[0003] Chinese patent discloses a dry pulverizer (authorization announcement number CN2514910Y). This patented technology includes a base, a motor, a grinding seat with a discharge hopper, an adjusting sleeve, and a cover plate with a feed hopper and cooling water nozzle. Rotary teeth are installed inside the grinding seat, which is connected to the motor flange, and are fixed to the motor shaft. A fixed tooth assembly is fixed inside the cover plate with the adjusting sleeve. On two conical surfaces opposite the fixed tooth assembly and the rotating teeth, evenly distributed oblique teeth with triangular or trapezoidal cross-sections are arranged. A feeder, assembled in the cavity between the fixed tooth assembly and the rotating teeth, is fixed to the motor shaft. It features a simple structure, small footprint, low cost, low noise, and significantly improved pulverizing effect.

[0004] This patented technology has the advantage of high-efficiency crushing, but there are still shortcomings in its use. The crushed material particles are generally uniform, but there are still some incompletely crushed and larger particles, which affects the use. There is no effective screening device to screen the crushed material. Therefore, those skilled in the art have provided a high-speed crusher to solve the problems mentioned in the background art. Utility Model Content

[0005] 1. Technical Solution

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a high-speed pulverizer, including a support frame.

[0008] The crushing structure includes a crushing box, a motor located above the crushing box, a rotating shaft located at the output end of the motor and rotatably installed inside the crushing box, blades located on the outer wall of the rotating shaft and arranged in a ring array, a guide bucket fixedly placed at the lower end of the screen cylinder, and a bracket sleeved on the outer wall of the motor and fixedly installed with the support frame.

[0009] as well as;

[0010] The screening structure includes a screen cylinder, a filter screen fixed to the inner wall of the screen cylinder, a telescopic sleeve fixed to the upper end of the screen cylinder and sleeved on the outer wall of the crushing box, a support ring sleeved on the outer wall of the screen cylinder, springs fixed between the support frame and the support ring and arranged in a ring array, mounting columns fixed to the upper end of the support ring and arranged symmetrically, a side rod located on the outer wall of the rotating shaft and sleeved on the outer side of the screen cylinder, and a guide bucket fixed to the lower end of the screen cylinder.

[0011] Furthermore, the lower ends of the first and second guide buckets are respectively provided with a first discharge pipe and a second discharge pipe, and both the first and second discharge pipes are provided with control valves.

[0012] Specifically, discharge pipe one outputs the material at the top of guide bucket one, and discharge pipe two outputs the material at the top of guide bucket two. The opening and closing of discharge pipe one and discharge pipe two are controlled by a control valve.

[0013] Furthermore, both the filter screen and the flow guide hopper are embedded with a sliding sleeve, and the sliding sleeve has a support column whose upper and lower ends are respectively connected to the flow guide hopper and the support frame.

[0014] Specifically, the support column is slidably installed inside the guide bucket and filter screen via a sliding sleeve, supporting the guide bucket and the crushing box connected to the guide bucket. When the filter screen shakes longitudinally, it effectively slides on the outer wall of the support column via the sliding sleeve.

[0015] Furthermore, a feed pipe is provided on one side of the upper end of the screen cylinder, and a sealing cap is provided inside the feed pipe;

[0016] Specifically, the material is fed into the crushing chamber through the feed pipe, and the feed pipe is closed by a sealing cover.

[0017] Furthermore, the inner wall of the sieve cylinder is provided with a gear ring, the outer wall of the rotating shaft is fitted with a gear one, the gear ring is meshed with a gear two that meshes with the gear one, the gear two is provided with a stirring shaft inside, and a push plate fitted to the outside of the blade is provided on one side of the lower end of the stirring shaft.

[0018] Specifically, when gear one drives gear two to rotate, gear two, because it meshes with the gear ring, rotates on its own axis while also revolving around the center, driving the pusher plate to push the material and assisting in the flow of the material.

[0019] Furthermore, a cleaning port is provided at one end of the screen cylinder, and a valve seat is provided on the outer wall of the screen cylinder located on the side of the cleaning port. A valve plate is slidably installed inside the valve seat, and a second sliding sleeve is embedded inside the valve seat. An insert rod is slidably installed inside the second sliding sleeve. A locking block is provided at the lower end of the insert rod, and a limiting block is sleeved on the outer wall of the insert rod. A compression spring sleeved on the outside of the insert rod is provided between the limiting block and the valve seat, and a pull handle is provided at the upper end of the insert rod.

[0020] Specifically, the cleaning port intercepts large particles of material at the top of the screen, and the opening and closing of the valve plate is controlled by the valve plate, which is positioned by a spring that provides elastic support.

[0021] Furthermore, a ball bearing is rotatably mounted on the upper end of the mounting column, a pressure ball is rotatably mounted on the lower end of the side rod, a through hole distributed in a ring array is opened inside the support ring, and a guide rod is provided on the upper end of the support frame, which is located inside the spring, distributed in a ring array, and slidably inserted into the through hole.

[0022] Specifically, when the side rod rotates past the mounting post, the pressure ball contacts the ball bearing to reduce frictional resistance. When the spring moves longitudinally, the guide rod slides inside the through hole to limit the spring and prevent it from shifting outward.

[0023] 2. Beneficial effects

[0024] Compared with existing technologies, the advantages of this utility model are:

[0025] In this invention, a motor drives a rotating shaft to rotate, which in turn drives the blades to crush the material inside the crushing chamber. After crushing, the material is conveyed to a filter screen, where it is screened. Qualified material passes through the filter screen, while unqualified large particles are intercepted, thus preventing the crushing of unqualified material from affecting its use.

[0026] Meanwhile, during the screening process, the motor still drives the side rod to press against the mounting column, which in turn presses against the elastically mounted screen cylinder, causing the filter screen to shake. During the screening process, the material jumps, which helps to screen the material and improves the situation of material blockage. The crushing and screening are combined into one device, which is convenient to use, avoids the separate screening process, and reduces the cost of equipment use and energy consumption.

[0027] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0043] Example 1

[0044] Please see Figures 1-6 As shown, this embodiment is a high-speed pulverizer, including a support frame 100.

[0045] The crushing structure 200 includes a crushing box 202, a motor 201 located above the crushing box 202, a rotating shaft 203 located at the output end of the motor 201 and rotatably installed inside the crushing box 202, blades 204 located on the outer wall of the rotating shaft 203 and arranged in a ring array, a guide bucket 208 fixedly placed at the lower end of the screen cylinder 305, and a bracket 207 sleeved on the outer wall of the motor 201 and fixedly installed with the support frame 100.

[0046] The lower ends of the first guide bucket 208 and the second guide bucket 306 are respectively provided with the first discharge pipe 209 and the second discharge pipe 321, and both the first discharge pipe 209 and the second discharge pipe 321 are provided with control valves.

[0047] Both the filter screen 320 and the flow guide hopper 206 have a sliding sleeve 211 embedded inside. Inside the sliding sleeve 211, there are support columns 210 whose upper and lower ends are respectively connected to the flow guide hopper 208 and the support frame 100.

[0048] A feed pipe 215 is provided on one side of the upper end of the screen cylinder 305, and a sealing cover 216 is provided inside the feed pipe 215;

[0049] The inner wall of the sieve cylinder 305 is provided with a gear ring 212, and the outer wall of the rotating shaft 203 is fitted with a gear 213. The gear ring 212 is meshed with a gear 214 that meshes with the gear 213. The gear 214 is provided with a stirring shaft 205. A push plate 206 is provided on one side of the lower end of the stirring shaft 205 and is fitted with the outside of the blade 204.

[0050] The crushing structure 200 is used;

[0051] Material is fed into the crushing chamber 202 through the feed pipe 215. The motor 201 drives the rotating shaft 203 to rotate, which in turn drives the blades 204 to crush the material. During the crushing process, the rotating shaft 203 drives the gear 1 213 to rotate, which in turn drives the gear 214 to rotate and rotate along the gear ring 212. While rotating on its own axis, the gear 214 rotates with the rotating shaft 203. The gear 214 drives the push plate 206 to rotate, which pushes the material during the crushing process, thereby helping the material flow. The material's fluidity is improved during crushing, which helps the material to be crushed more evenly.

[0052] Example 2

[0053] Please see Figures 1-6 As shown, this embodiment further includes elements beyond those in embodiment 1;

[0054] as well as;

[0055] The screening structure 300 includes a screen cylinder 305, a filter screen 320 fixed to the inner wall of the screen cylinder 305, a telescopic sleeve 302 fixed to the upper end of the screen cylinder 305 and sleeved on the outer wall of the crushing box 202, a support ring 301 sleeved on the outer wall of the screen cylinder 305, a spring 307 fixed between the support frame 100 and the support ring 301 and arranged in a ring array, mounting columns 303 fixed to the upper end of the support ring 301 and symmetrically distributed, a side rod 318 located on the outer wall of the rotating shaft 203 and sleeved on the outer side of the screen cylinder 305, and a guide bucket 306 fixed to the lower end of the screen cylinder 305.

[0056] A cleaning port 317 is provided at one end of the screen cylinder 305. A valve seat 311 is provided on the outer wall of the screen cylinder 305, located on the side of the cleaning port 317. A valve plate 312 is slidably installed inside the valve seat 311. A sliding sleeve 314 is embedded inside the valve seat 311. An insert rod 310 is slidably installed inside the sliding sleeve 314. A locking block 313 is provided at the lower end of the insert rod 310. A limiting block 316 is sleeved on the outer wall of the insert rod 310. A compression spring 315 is sleeved on the outside of the insert rod 310 between the limiting block 316 and the valve seat 311. A pull handle 309 is provided at the upper end of the insert rod 310.

[0057] A ball bearing 304 is rotatably mounted on the upper end of the mounting post 303, a pressure ball 319 is rotatably mounted on the lower end of the side rod 318, a through hole distributed in a ring array is opened inside the support ring 301, and a guide rod 308 is provided on the upper end of the support frame 100, which is located inside the spring 307, distributed in a ring array, and slidably inserted into the through hole.

[0058] The screening structure 300 is used;

[0059] After the material is crushed, it is conveyed into the screen cylinder 305 through discharge pipe 209. The material is then screened through the filter screen 320. While screening, the motor 201 continues to operate, and new material can be input into the screen cylinder 305. The control valve is a solenoid valve, which can be remotely controlled. Controlling discharge pipe 209 opens discharge pipe 321, and the motor 201 drives the rotating shaft 203 to rotate, causing the side rod 318 to rotate. When the side rod 318 drives the pressure ball 319 through the ball bearing 304, the support ring 301 is compressed against the spring 307. When the pressure ball 319 passes through the ball bearing 304, the spring 307 returns to its original position due to its elasticity, causing the support ring 301 to rotate. The shaking causes the filter screen 320 to shake as well. Small, qualified particles of material on the filter screen 320 pass through the filter screen 320 during the shaking. At the same time, the telescopic sleeve 302 extends and retracts to ensure the shaking of the screen cylinder 305. The telescopic sleeve 302 also intercepts the material jumping during the screening process. The material is crushed and screened at the same time, and the crushing and screening use the same motor 201, which reduces the cost of using the equipment and reduces energy consumption. At the same time, the quality of the material after screening is improved, avoiding the impact of large, incompletely crushed materials on the use. The push plate 206 mixes the material during crushing, which also reduces the situation of incomplete crushing. The crushing equipment achieves high efficiency and convenient use.

[0060] After using the equipment, grip the handle 309 to lift the insertion rod 310. The compression spring 315 extends under force, causing the locking block 313 to disengage from one side of the valve plate 312. The valve plate 312 slides out of the valve seat 311 and cleans the upper end of the filter screen 320 through the cleaning port 317. After cleaning, insert the valve plate 312 back in and relax the lifted insertion rod 310. With the elastic support of the compression spring 315, the locking block 313 is pushed to lock and position the valve plate 312, preventing the valve plate 312 from disengaging. The cleaning port 317 is closed when the equipment is in use.
